The Mercedes-Benz C-Class not only meets the highest demands in terms of safety, comfort, agility, and design, but also shows significant improvements regarding the examined environmental aspects over the entire lifecycle compared to the predecessor.
Life Cycle Assessment
The plug-in hybrid model in the current C-Class, the C 350 e (Combined fuel consumption (petrol): 2.4–2.1 l/100 km; combined CO₂ emissions: 54–48 g/km*), combines a 60 kW electric motor and an externally rechargeable battery with a four-cylinder petrol engine with 155 kW displacing just under two litres. Production of the C 350 e entails a visibly higher level of carbon dioxide emissions, on account of the additional hybrid-specific components.
External charging with the European electricity grid mix can cut CO₂ emissions by around 14 percent (approx. 5 tons ) compared to the C 250 petrol model (Combined fuel consumption (petrol): 5.8–5.3 l/100 km; combined CO₂ emissions: 135–123 g/km*). A 41 percent reduction (approx. 15 tons ) is possible through the use of renewably generated electricity from hydro power.

Secondary and renewable raw materials
In the new C-Class, 52 components with an overall weight of 49.3 kilograms can be manufactured partly from high-quality recycled plastics. The weight of secondary raw material components could thus be increased by 23 percent compared with the preceding model. Typical areas of use are wheel arch linings and underbody panels, which consist for the most part of polypropylene.
In automotive production, the use of renewable raw materials is concentrated primarily in the vehicle interior. Established natural materials such as cellulose and wood fibres, wool, cotton and natural rubber are also used, of course, in series production of the C-Class. In the new C-Class, a total of 76 components with an overall weight of 26.3 kilograms are made using natural materials.
The total weight of components manufactured with the use of renewable raw materials has thus increased by 55 percent compared with the preceding model.
Allergy-tested car cabin
The current C-Class has also been awarded the Seal of Quality from the European Centre for Allergy Research Foundation (ECARF).
The ECARF Seal of Quality is used by ECARF to designate products that have been scientifically tested and proven to be suitable for allergy sufferers.
